Question

The mass and volume of a body are 4.237 g and 2.5 cm3 , respectively. The density of the material of the body in correct significant figures is
(a) 1.6048 g cm^–3
(b) 1.69 g cm^–3
(c) 1.7 g cm^–3
(d) 1.695 g cm^–3

Answer 1

density = mass/volume = 4.237*2.5 = 1.6948 g cm^-3 = 1.7 g cm^-3
as the minimum significant figure is 2

Answer 2

Explanation:

• So the result obtained after multiplication and division will have same number of significant figures as in original number with least significant figure.
• So density of the material = mass / volume.
•                   Or ꝭ = m/v
•                            = 4.237 g / 2.5 cm^3
•                            = 1.6948 g/cm^3
• Now the number of significant figure needs to be 2 since the original or least significant figure is 2.
• So the right hand side after the point is 69 and 9 is greater than 5.
• Therefore we get density ꝭ = 1.7 g/cm^3
